You could try the symbolic toolbox but I don't know how successful it'll be.
Basically, you need to write a function that computes enough terms of the series that it converges to some chosen level of accuracy.

Symbolic Math Toolbox may be used to implement the above equation in MATLAB. Here are a few suggestions which may be helpful in the implementation
- Declare “n” as a symbolic variable and “N” as a symbolic function of two variables “x” and “t” using the following syntax
syms n N(x,t)
- To implement the summation term, use the following code
F = exp(-((2*n+1)*pi)^2*D*t/L^2)*sin((2*n+1)*pi*x/L)/((2*n+1)*pi^3);
Fsum = symsum(F,n,0,inf);
Here “n” is replaced by “2n+1” so that only odd terms are considered in the summation.
The function “symsum()” sets the limits of summation from 0 to inf.
Remaining terms can be written as normal equation in MATLAB
Please use the following documentation links on how to create symbolic functions and “symsum()” to get a better understanding
